Abstract: In this paper,the calculation of the pressure loss of the telescopic pipe used in the firefighting vehicle was analyzed and studied, and a calculation flow of pipeline optimization was proposed. By using this method, the pressure loss characteristics of stainless steel pipeline and aluminum alloy pipeline were analyzed respectively. Through this calculation, the goal of pipeline weight reduction and pressure loss reduction was realized. Finally, the impact of the boom deformation on the optimization results was analyzed in detail to ensure the safety demand during the usage of high-rise aerial platform fire fighting vehicle.
